You Are Prompted to Reinstall Programs After You Remove Windows 2000 SP1 or SP2 (320256)
The information in this article applies to:
- Microsoft Windows 2000 Professional SP1
- Microsoft Windows 2000 Professional SP2
This article was previously published under Q320256 SYMPTOMS After you remove Windows 2000 Service Pack 1 (SP1) or
Service Pack 2 (SP2), you may be prompted to reinstall programs that use the
Windows Installer program. For example, if you install Microsoft Office 2000
Premium SR-1 from a CD-ROM (but the Office CD-ROM is not currently in your
CD-ROM drive), you may receive the following prompt when you restart your
computer after you remove Windows 2000 SP2: Office
This application must be installed to run. Please run Setup from the location
where you originally installed the application. If you try to run an
Office program, you may receive the following message:
Windows Installer
The feature you are trying to use is on a CD-ROM or
other removable disk that is not available.
Insert the 'Microsoft
Office SR-1 Premium' disk and click OK. CAUSE This behavior can occur if you updated the Windows
Installer program to version 2.0 by running the Windows Installer 2.0
Redistributable package, or by installing a program that redistributes the
Windows Installer program (for example, Microsoft Visual Studio
.NET).
If you remove Windows 2000 SP1 or SP2, Windows Installer 1.1
files are restored over the Windows Installer 2.0 files. The Windows Installer
1.1 files cannot read the Windows Installer 2.0 database from the registry
because the format has changed. RESOLUTION To resolve this issue, click Cancel when you are prompted to reinstall programs that use the Windows
Installer program, and then install the Windows Installer 2.0 Redistributable
package for Microsoft Windows NT 4.0 and Windows 2000 from the following
Microsoft Web site: STATUSMicrosoft has confirmed that this
is a problem in Windows 2000 SP1 and SP2.
MORE INFORMATION Microsoft does not recommend removing Windows 2000 SP1 or
SP2 if Windows Installer 2.0 is installed. To determine which version of
Windows Installer is installed, check the version of the Msi.dll file. Version
number 2.0.2526.0 or later indicates that Windows Installer 2.0 is
installed.
Note that Windows 2000 Service Pack 3 (SP3) installs
Windows Installer 2.0, and it is not an optional component. Windows Installer
2.0 in SP3 is also not removable. Therefore, removing SP3 does not remove
Windows Installer 2.0.
